Advantages Of EINK
E-paper display utilizes microcapsule electrophoretic technology for displaying, the principle is: charged particles suspended in clear fluid will move to sides of microcapsule when electric field is applied, making the microcapsule become visible by reflecting ambient light, just as traditional printed paper.
E-paper display will clearly display images/texts under lamplight or natural light, requires no backlight, and features nearly up to 180° viewing angle. It is usually used as e-reader due to its paper-like effect.
Standard Raspberry Pi 40PIN GPIO Header
Compatible With Raspberry Pi Series Boards, Jetson Nano
Onboard SPI Control Interface
For Use With Other Controller Boards Like STM32/Arduino
VCC | 3.3V/5V |
GND | Ground |
DIN | SPI MOSI pin |
CLK | SPI SCK pin |
CS | SPI chip selection, low active |
DC | Data / Command selection (high for data, low for command) |
RST | External reset, low active |
BUSY | Busy status output, high active |
* for Arduino UNO, due to its RAM limit, it is better to choose the e-Paper Shield
